Required Methods
Retrieves the name of the currently selected font. This name includes
style and size information as well. If you want to render something
with the font, use this string with pango::FontDescription::from_string() .
If you’re interested in peeking certain values (family name,
style, size, weight) just query these properties from the
pango::FontDescription object.
Deprecated since 3.22
Use FontChooserExt::font() instead
Returns
an internal copy of the font name which must not be freed.
fn shows_size(&self) -> bool
fn shows_size(&self) -> bool
Returns whether the font size will be shown in the label.
Returns
whether the font size will be shown in the label.
fn shows_style(&self) -> bool
fn shows_style(&self) -> bool
Returns whether the name of the font style will be shown in the label.
Returns
whether the font style will be shown in the label.
Retrieves the title of the font chooser dialog.
Returns
an internal copy of the title string which must not be freed.
Returns whether the selected font is used in the label.
Returns
whether the selected font is used in the label.
Returns whether the selected size is used in the label.
Returns
whether the selected size is used in the label.
fn set_font_name(&self, fontname: &str) -> bool
fn set_font_name(&self, fontname: &str) -> bool
Sets or updates the currently-displayed font in font picker dialog.
Deprecated since 3.22
Use FontChooserExt::set_font() instead
fontname
Name of font to display in font chooser dialog
Returns
fn set_show_size(&self, show_size: bool)
fn set_show_size(&self, show_size: bool)
fn set_show_style(&self, show_style: bool)
fn set_show_style(&self, show_style: bool)
If show_style is true, the font style will be displayed along with name of the selected font.
show_style
true if font style should be displayed in label.
fn set_use_font(&self, use_font: bool)
fn set_use_font(&self, use_font: bool)
fn set_use_size(&self, use_size: bool)
fn set_use_size(&self, use_size: bool)
fn connect_font_set<F: Fn(&Self) + 'static>(&self, f: F) -> SignalHandlerId
fn connect_font_set<F: Fn(&Self) + 'static>(&self, f: F) -> SignalHandlerId
The ::font-set signal is emitted when the user selects a font.
When handling this signal, use FontChooserExt::font()
to find out which font was just selected.
Note that this signal is only emitted when the user changes the font. If you need to react to programmatic font changes as well, use the notify::font signal.
